1. When using the Ballard gestational assessment tool on a newborn, which of the following tests should be performed after the first hour of birth, allowing the newborn to recover from the stress of birth?

• A. Arm recoil
• B. Square window sign
• C. Scarf sign
• D. Popliteal angle

Correct answer: A

Rationale: The correct answer is Arm recoil. Arm recoil is slower in healthy but fatigued newborns after birth, making it best elicited after the first hour of birth when the baby has had time to recover from the stress of birth. This assessment helps evaluate neuromuscular maturity in newborns and is more accurate when performed after the initial recovery period. The other choices, Square window sign, Scarf sign, and Popliteal angle, are not specifically assessed using the Ballard gestational assessment tool and do not relate to the recovery period after birth.

2. When a father asks why his child with tetralogy of Fallot seems to favor a squatting position, the nurse would explain that squatting:

• A. Increases peripheral vascular resistance
• B. Decreases arterial blood flow away from the heart
• C. It's a common resting position when a child is tachycardic
• D. Increases the workload of the heart

Correct answer: A

Rationale: Squatting increases systemic vascular resistance, which leads to a reduction in the right-to-left shunting of blood in children with tetralogy of Fallot. This helps improve oxygenation by balancing the pulmonary and systemic blood flow. The squatting position decreases the pressure in the right ventricle and reduces the magnitude of the right-to-left shunt by increasing afterload, thereby improving oxygenation. Choices B, C, and D are incorrect because squatting does not decrease arterial blood flow away from the heart, is not related to being tachycardic, and does not increase the workload of the heart.

3. How will a ventricular septal defect affect blood flow?

• A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
• B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
• C. No shunting occurs due to high pressure in the left ventricle.
• D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.

Correct answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.

4. You are treating a 5-year-old child who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. Supplemental oxygen has been given, and you have elevated his lower extremities. En route to the hospital, you note that his work of breathing has increased. You should:

• A. begin positive-pressure ventilations and reassess the child.
• B. lower the extremities and reassess the child.
• C. listen to the lungs with a stethoscope for abnormal breath sounds.
• D. insert a nasopharyngeal airway and increase the oxygen flow.

Correct answer: B

Rationale: When the work of breathing increases after elevating the legs, it is important to lower the extremities. Elevating the lower extremities in a child with signs of shock can worsen the condition by reducing venous return to the heart. Lowering the extremities can help improve venous return and potentially alleviate the increased work of breathing.

5. Before drying off the newborn after birth, which assessment finding should the healthcare professional document to ensure an accurate gestational rating on the Ballard gestational assessment tool?

• A. Amount and area of vernix coverage
• B. Creases on the sole
• C. Size of the areola
• D. Body surface temperature

Correct answer: A

Rationale: To ensure an accurate gestational rating on the Ballard gestational assessment tool, healthcare professionals should document the amount and area of vernix coverage before drying the newborn. Drying the baby after birth could disturb the vernix, potentially affecting the gestational age assessment. Assessing and documenting the vernix coverage beforehand enables a more precise evaluation using the Ballard gestational assessment tool. Choices B, C, and D are incorrect as they are not directly related to gestational rating on the Ballard assessment tool.
